Rivet 30' Excella 1993 wheel bearings

Well let's start with the PO had the bearings repacked last year and dragged the Airstream from Cape Cod with a VW Vanagon 6cyl (that's another story) to Naples Florida. After I got it, I towed it around short hops then struck out for the North and noticed a grease smell after 180 miles and the left rear wheel was 18 degrees hotter than the rest with a Laser temp meter. Checking it the over the next 600 miles it started to run cooler, just 7 degrees hotter when home. Just pulled that wheel today and found the bearing started to gall. I think the mechanic over tightened the castle nut but have never seen KOYO bearings, I'm thinking replace all four to be safe. Where is the best place to get them for a 12x2 Dexter brake drum, parts are daunting since a dealer is hundreds of miles away. Limited budget, Any suggestions?

I bought bearings at NAPA. Made in Mexico. About $30 for each set. Another 5 for the seals. Not sure where to get USA bearings. NAPA and other places can cross reference the bearings and seals from the old parts numbers. I think they had some Chinese ones too, so pay attention.

Here is the link to our maintenance page on our website that has the Timken part numbers. Northern Illinois Maintenance

I hope this is of some use.

Timken bearings

I think Timken is a Japanese manufacturer now,sadly.Still a superior product to the competitors.

The outer bearing number is 15123.

The inner bearing number is 25580.

Dealers that stock parts would have those bearings.

Today, at least with bearings, the failure rate is extremely small, overall.

American and/or foreign bearings all seem to work just fine.

Make sure you use double lipped grease seals that also have a spring in them.
